개요

NXP’s UCODE 7 IC is the leading-edge EPC Gen2 RFID chip that offers best-in-class performance and features for use in the most demanding RFID tagging applications.

UCODE® 7m is a derivative of the UCODE 7 and offers on top of the UCODE 7 features a 32-bit User Memory.

Particularly well suited for inventory management application, like e.g Retail and Fashion, with its leading-edge RF performance for any given form factor, UCODE 7 enables long read distance and fast inventory of dense RFID tag population. With its broadband design, it offers the possibility to manufacture true global RFID label with best-in-class performance over worldwide regulations.

The device also provides a pre-serialized 96-bit EPC and a Parallel encoding feature. For applications where the same 58-bit Stock Keeping Unit (SKU) needs to be encoded on multiple tags, at the same time, a combination of both features improves and simplifies the tag initialization process.

On top UCODE 7 offers a Tag Power Indicator for RFID tag initialization optimization and a Product Status Flag for Electronic Article Surveillance (EAS) application.

Supported features

The following optional commands are implemented in conformance with the EPC specification:

Access

BlockWrite (2 words, 32-bit)

Product Status Flag bit: enables the UHF RFID tag to be used as EAS (Electronic Article Surveillance) tag without the need for a back-end database.

Tag Power Indicator: enables the reader to select only ICs/tags that have enough power to be written to.

Parallel encoding: allows for the ability to bring (multiple) tag(s) quickly to the OPEN state and hence allowing single tags to be identified simply, without timing restrictions,or multiple tags to be e.g. written to at the same time, considerably reducing the encoding process

All supported features of UCODE 7 can be activated using standard EPCglobal READ / WRITE / ACCESS / SELECT commands. No custom commands are needed to take advantage of all the features in case of unlocked EPC memory. The parallel encoding feature may however require a firmware upgrade of the reader to use its full potential.
